12.6.1 PERC H200 Modular

The PERC H200 Modular card is an expansion controller that incorporates two four-channel 6 Gb/s
SAS IOCs for connection to SAS hard disk drives. It is designed in a form factor that allows the same
card to be used in other 11G blade-server platforms.

12.6.2 PERC H700 Modular

The M915 also supports the PERC H700 Modular storage controller card with battery-backed cache.
The PERC H700 card has its own processor with a PCI Express Gen2 host interface and DDR2 memory.
